Humpf!! Reaper7 does have a sub image on the inner dial!

I didn't notice it before. I can see where there could be some confusion over just what are we looking at if the AoB inner most dial has a sub image on it. The image should be thought of as the target ships, not your own subs image.

The Angle on Bow is always taken (or read) from the target ship, not from the subs point of view. The only point of view the sub has is the "relative bearing" of the target which is gained by determining from what position the target is in relationship to the sub (get the "relative/relationship" connection?). The bow of the sub represents the zero degree mark on the compass dial, 90 degree is directly to the right or starboard, 270 degree relative bearing is directly to the left or port of the sub. 180 degree is to the rear or stern of the sub. AoB of the target ship relates to the compass in the same way but when you say the "AoB is 90 degrees port", it means the sub is positioned directly to the right of the target ship (from the target ships point of view).

I can see where it's a bit confusing if the image on the dial looks like the sub, and not of the target ship as it should represent.
